IRR and MOIC calculator

Enter what you put in and what you got back, and when. You'll see the internal rate of return (IRR) next to the multiple on invested capital (MOIC), because each one can flatter a deal the other exposes.

Year 0 is the day you invest. Use decimals for partial years: 0.5 is six months. Put the same year on two rows if money went in and out at once.

Fees work like an advisory or management fee, a yearly drag on what you get back. Inflation restates everything in the dollars you invested.
What you could realistically earn on distributions. Used for the modified IRR.

Cash over time

Your cumulative position: down while money goes in, climbing as it comes back. Where it crosses zero is when you got your money back.

What IRR doesn't tell you

IRR measures speed, not size, and it quietly assumes every distribution is reinvested at the same IRR. These three checks keep it honest.
